To be honest if your budget is very limited I wouldn't recomend boost.

900-1000 pounds equals what in american currency?
If you really want to go turbo do your self a favor, do NOT go with the e-bay crap, sure it's cheap and it will get you going, but consider it a waste of about $700. Almost everything will have to be replaced eventually.
If it's from ssautochrome you'll be replacing it a lot sooner then you want.
Take your time and buy quality used parts, once you get everything then put it on. Doing it half ass will only get you a blown motor, and empty pockets....
I'm not trying to talk you out of doing this, but I'd hate to see a post from you saying "help my motor sounds like shit and smokes like crazy whats wrong" or "help my manifold cracked/turbo seized up/car runs like shit/etc"

There are two rules that I always recomend and follow..
1) K.I.S.S (keep it simple stuipid) 10 hack devices to make your turbo set-up work half ass is not simple. Hondata, higher flow fuel pump and larger injectors is simple.
2) NEVER skimp on the tuning. If you want a blown motor cheap out on it and spend the money you saved on tuning to rebuild your engine....
It comes down to this.
Cheap
Fast
Reliable.... pick two and sacrifice the other....
There are exception, but very few and they are far and few in between....
Oh and those e-bay kits, most don't come with an intercooler or any form of fuel management....thats another cost you must add on to it. The only thing worth anything in the kit is the charge pipes, you cant really screw those up....they're pipes that are hollow and have bends:thinking:
